The Bosch Rexroth Z4WEH10E68-4X/6EW110N9TK4 (R901365483) is a high-performance directional spool valve designed for electrohydraulic actuation, providing precise control in fluid power systems. This model functions as either a shutoff through valve or shutoff short-circuit through valve, ensuring versatility in its application. The Z4WEH10E68-4X/6EW110N9TK4 allows for P and T free flow in every spool position, enhancing its operational flexibility. The valve's porting pattern adheres to ISO standards, ensuring compatibility with a wide range of equipment and systems. It is equipped with wet-pin DC or AC solenoids, which can be optionally chosen based on the specific requirements of the application. For further customization, an optional auxiliary operating device can be added to the setup. Electrical connections are designed for either individual or central connection as per the requirements outlined in RE specifications. The model also provides optional features such as switching time adjustment and stroke setting at the main spool, allowing for tailored control over the hydraulic system's response and performance. Additionally, the Z4WEH10E68-4X/6EW110N9TK4 can be fitted with inductive position switches and proximity sensors for contactless detection of spool position, enhancing precision and reliability. It supports a maximum operating pressure of up to X bar and can handle maximum flow rates of l/min as per order specifications. This Bosch Rexroth directional spool valve is an essential component for various hydraulic applications requiring robust performance and precise control. Its advanced features and customizable options make it suitable for sophisticated hydraulic systems where reliable actuation is critical.

Notices!

Actuation of the manual override is only possible up to a tank pressure of approx. 50 bar. Avoid damage to the bore of the manual override! (Special tool for the operation, separate order, material no. R900024943). When the manual override is blocked, the actuation of the solenoid must be prevented! The simultaneous actuation of the solenoids must be prevented!

Stroke setting, mounting options

The stroke of the main spool is limited by the stroke setting.

The piston stroke is shortened by untightening the lock nut (17) and clockwise rotation of the adjustment spindle (18). For this, the control chamber has to be depressurized.

Stroke 6 mm (1 rotation = 1 mm stroke)
